Description

Locking mechanism and locking method for commodity anti-theft

Technical Field

The invention relates to the field of commodity theft prevention, in particular to a locking mechanism and a locking method for commodity theft prevention.

Background

With the development of commodity experience type services, the display and experience functions of commodities are more opened to purchasers or potential purchasers, and meanwhile, the requirement for commodity theft prevention is continuously increased. On the one hand, the various requirements of the experience person are met as much as possible, all functions of the commodity and the side which is the most good and convenient are displayed to the experience person as much as possible, on the other hand, the possible stealing behaviors of the person who is in good care are prevented, and the hidden danger that the commodity is possibly stolen in the displaying and experiencing process is reduced or even eliminated as much as possible.

In the commodity display anti-theft industry, due to the difference of domestic and foreign manpower price cost and display environment, the demand of domestic and foreign anti-theft devices is greatly different. For example, many retail stores, telecom business halls and large merchants in the united states and france have higher labor cost, and in-store maintenance staff are fewer, so that a 'grab + escape' theft event often occurs, namely, after a thief enters a store, the thief pulls out or cuts off a connecting line without paying attention to the shop staff, steals a commodity being displayed, and escapes the theft event, so that the theft-proof level of the burglar alarm is required to be higher. Therefore, trade companies in the industry have precedents or products for locking and connecting wires by using screws, which can effectively meet the requirements of many strong anti-theft markets abroad.

However, the large domestic display environments are quite different, many retail display shops in China, such as Hua ' e, millet, telecom and the like, have more salesmen and customers in the shops, and in addition, most shops are in a busy central area with complicated stream of people and traffic, and the event of ' grabbing up and escaping ' by thieves rarely occurs, so that the strong anti-theft requirements for the display burglar alarm in China, such as the functional requirements for screw locking are less, and the addition of screw locking increases unnecessary labor cost for the retail shops.

Therefore, the great difference of the domestic and foreign product demands leads the anti-theft device manufacturers in the industry to carry out complicated distinguishing and management on the same product, such as the design, production and storage of wire rods, thereby greatly increasing the cost of manpower and material resources.
